Document Photography In Vitro
Experiments on evaluating and improving the mechanical configuration and target illumination in a prototype camera-based ballot counter are presented. The constraints on the mechanical design are gravity paper feed, portability, ease of use and low cost. The constraints on illumination are dictated by image processing requirements. Initial results are reported on the effects of transparent ballot cover plates, geometry, and light conditioning (color, diffusion, polarization).
